Also known as a "base tune." You're arguing semantics at this point, I agreed with you right off the bat that an in person tune will yield better results. But some people may not have a dyno shop in their area, and a base tune that's altered for a different cam is going to be much better than trying to run it on the stock tune. Could be the difference between getting a vehicle mobile under it's own power to drive it to a shop with a dyno or having to trailer it there.
Whatever you want to call it, I can confirm personally that Black Bear Performance's tuning works wonders on the '96+ black box trucks. Even in relatively stock form. I'm sure they could at least get a new cam setup running well if OP has a '96+ PCM.
in no way am i knocking black bear. never even heard of them before. your base tune and mine are different.it is a base map, because everytime you write to eprom you are creating a new map or altering someone elses map. base is done immediately after build or mods are added. it is to prevent catastrophic damage. it is also to allow break in on a dyno or an empty stretch of highway (dont try this at home) or the track. usually mediocre timing, very slightly rich on fuel.
what i try to say to help the folks that think they can be included in the cool group at the mall, and just throw in any cam, and other mods, is that they can destroy their engine and/or cause terrible running conditions. they look for a "exhaust chop" , i say there ia unlikely any "chop" on a well tuned correctly build modern day DAILY DRIVEN, RELIABLE engine. i see it on youtube alot, even what apears to be a promod or street outlaw type that is idled way too low, way too rich, and idled wayyyyy too long with ragged acelerator blips. thats it, thats the show, and junior is watching this junk and thinking how cool he would be if he put that in his pickup truck. why is it that none of these ever show a real dyno run, or printed sheets that show run parameters, or track results? shiny objects attract more *****. a fool and his money are soon parted, yada yada
where is the data library where folks are getting these base maps? it would be fun to lookie at some. it would also be fun to look at runfiles before and after and from different shops/tuners
i just try and tell the facts and maybe some will do more learning off-net and read books, learn formulas, apply knowledge.
and at times i dont communicate well (pesky stroke) and it takes to long to make a coherent argument on a keybourd, so i short shift and hurry up to finish typing
peace
